eyes.

recommended to keep still during heart rate detection. Otherwise, it may take a longer
time to measure the heart rate or you may get incorrect data. After the watch has
measured the data, you can do exercise again and view the dynamic data.

measurement. If you make 5 successive measurements and take their average value, you
will get a correct result.

values when you are in different states (talking, eating, and drinking). The real heart rate
value depends on the actual situation.

detection result.

Therefore, its precision may vary with the physiological factors (blood circulation, blood
pressure, skin conditions, blood vessel location and density) which affect light
absorption and reflection. When the measured heart rate value is very great or very small,
the measurement value may be incorrect and you need to make another measurement.
4.10 Long-time measurement may cause the watch to get hot. If this makes you
